St. Peter's Basilica Dome - Vatican City in Rome

Perhaps the most recognizable building of Vatican City, St. Peter's Basilica is the main Church of the Vatican built and named under the words of Jesus to St. Peter:

"And Jesus answered and said unto him, Blessed art thou, Simon Bar-Jonah, for flesh and blood hath not revealed it unto thee, but My Father who is in Heaven.And I say also unto thee, that thou art Peter, and upon this rock I will build My church; and the gates of hell shall not prevail against it. And I will give unto thee the keys of the Kingdom of Heaven. And whatsoever thou shalt bind on earth shall be bound in Heaven, and whatsoever thou shalt loose on earth shall be loosed in Heaven.”
